GitHub PR Review MCP Server

A modular MCP (Model Context Protocol) server that integrates GitHub Pull Request data, analyzes code changes using Anthropic's Claude Desktop, and saves PR review summaries to Notion.

Overview

This project demonstrates how to build an MCP server using Anthropic’s Model Context Protocol (MCP) to enable large language models (LLMs) like Claude to interact dynamically with external tools:

  • Fetch pull request details and changed files from GitHub.
  • Analyze PR code changes with Claude Desktop.
  • Create structured PR review documentation in Notion.

Features

  • Standardized MCP server architecture with modular tools.
  • GitHub integration for fetching PR metadata and diffs.
  • Notion integration for saving PR analysis as pages.
  • Uses Python, MCP, requests, notion-client, and python-dotenv.

Data Flow


   +---------------------------+
   | 1. User Input in Claude   |
   |    Desktop (PR Link)      |
   +------------+--------------+
                |
                v
   +---------------------------+
   | 2. MCP Client sends       |
   |    request to MCP Server  |
   +------------+--------------+
                |
                v
   +---------------------------+
   | 3. MCP Server runs fetch_pr|
   |    tool → Calls GitHub API|
   +------------+--------------+
                |
                v
   +---------------------------+
   | 4. GitHub API returns PR  |
   |    metadata & file changes|
   +------------+--------------+
                |
                v
   +---------------------------+
   | 5. Claude Desktop analyzes|
   |    PR data & generates    |
   |    review summary         |
   +------------+--------------+
                |
                v
   +---------------------------+
   | 6. User requests to save  |
   |    review → MCP Server's  |
   |    create_notion_page tool|
   +------------+--------------+
                |
                v
   +---------------------------+
   | 7. MCP Server calls       |
   |    Notion API to create   |
   |    page with summary      |
   +------------+--------------+
                |
                v
   +---------------------------+
   | 8. Notion page created in |
   |    configured workspace   |
   +---------------------------+
